[GUIDE] Rooting your Essential PH-1

WARNING: Before attempting to root your device, do note that by unlocking your bootloader and modifying your device with root, ROMs, etc... you are risking voiding your warranty! I am NOT responsible for what you do to your device either, so follow these instructions at your own risk. Make sure you know what you're doing, it's best to understand the process rather than just copy and paste commands and such.
Useful and important general information can be found in the second post here.
NOTES
1. If you flash the TWRP Installer when you've already got Magisk installed, your device will keep booting to the recovery. You should be able to fix this by just simply reflashing Magisk.
2. If you have TWRP installed via the TWRP Installer, you will not be able to install stock OTA updates. You will have to reflash the stock boot image for whatever build you're running beforehand.
3. The prebuilt TWRP image may not have touch functionality if you're using the September 2018 Update or newer. Patching the boot image, however, for these builds with the TWRP Installer will allow touch to work flawlessly. Here is a pre-patched September 2018 Boot Image with TWRP. It should also work with builds newer than September. Since it's based off the September 2018 update, I suggest not using this as your main boot image but rather just as a replacement for the pre-built TWRP image from the official TWRP thread.
4. Simple "flash and forget" boot images pre-patched with Magisk and TWRP are provided by @aer0zer0 and are available here. They are based on ianmacd's variant of Magisk. If you are running stock, you can flash these boot images to get root and TWRP instead of following the guide to patch it yourself. Here is January's.
If you don't care about TWRP and simply want to just root your device, you can just simply patch the boot image for your ROM with the Magisk Manager and flash it in fastboot with
Code:
fastboot flash boot patched_boot.img
The link to the boot images for most stock builds can be grabbed from my Google Drive link in the second post or from the back-to-stock zips.
REQUIREMENTS
An unlocked bootloader
Working adb and fastboot environment, along with knowledge on how they work.
The latest build of TWRP along with the TWRP Installer. Read Note 3 above beforehand.
1. Download the latest build of TWRP and the TWRP Installer. Transfer the TWRP Installer zip to your device.
2. Reboot your phone into fastboot. Once in fastboot, change your device's current slot using the command
Code:
fastboot set_active other
If the command above doesn't work for you, use fastboot getvar current-slot followed by fastboot -aX, replacing "X" with the slot opposite (a or b) from your current slot.
3. Once your device's current slot has been switched, flash the TWRP image you downloaded earlier using the command
Code:
fastboot flash boot twrp.img
Depending on your version of fastboot, the above command might not work either. In that case, you can enter the following command, replacing "X" with your current slot (a or b).
Code:
fastboot flash boot_X twrp.img
4. Once TWRP has been flashed, boot into the recovery.
5. Once you have booted into TWRP, simply flash the TWRP Installer zip.
6. Once you have finished flashing the TWRP Installer zip, boot to recovery on the OPPOSITE slot. You can do this from TWRP by going to "Reboot", then selecting the opposite of the current slot (if on A, select Slot B. If on B, select Slot A), then select "Recovery." You can also do this through fastboot by running the same command from step 2.
7. Once you have booted back into TWRP, simply flash the Magisk zip and you are now good to go! Feel free to flash anything else like kernels while you're at it.
8. Reboot. :good:
NOTE: TWRP WILL remain installed on your device so long as you reflash the installer zip after every update.

Important Information for the Essential PH-1 can be found here. Keep it bookmarked.
Tips on updating via OTA after rooting can be found here.
In the case that you mess something up on your device, you may find it helpful to revert back to stock with the unofficial factory images graciously provided by @invisiblek and @aer0zer0 over here.

Essential Phone (PH-1) Partition Layout
Dumping Boot Images
1. Find the current slot with
Code:
fastboot getvar current-slot
or
Code:
adb shell getprop ro.boot.slot_suffix
2. Switch to the opposite slot in Fastboot using the command
Code:
fastboot set_active other
3. Flash TWRP using the command
Code:
fastboot flash boot twrp.img
4. Now, boot into TWRP and use the following command from your PC, replacing X in "boot_X" with the original slot from step 1 (a or b). TRIPLE CHECK:
Code:
adb shell dd if=/dev/block/bootdevice/by-name/boot_X of=/sdcard/boot.img
5. Profit! Don't forget to switch back to the original partition with the same command from step 2!
extractTarFork() error when restoring data from a TWRP backup
1. Reinstall the ROM from which the backup is based on.
2. Wipe your data. You can do this from the recovery or from fastboot using the command
Code:
fastboot -w
3. Boot into the ROM. When going through the initial setup, use the EXACT same security setup as the one from your backup. For example, if you used a Fingerprint + Password in the backed up ROM, use the exact same combo along with the exact same password as well. There is no need to set up anything else, like accounts.
4. Flash, install, and reboot into TWRP. You should now be able to restore the data backup without any issues.

Thanks for getting the latest boot image up so quickly.

Thanks for the detailed guide, it worked great!
Any idea how to install xposed sdk 25? I tried the adb sideload function and the Magsik Module but both failed. Any ideas?

how to install the NMJ32F ota update when you are already rooted on NMJ20D?
Tried adb sideload but cannot install obviously because boot-loader is unlocked and is rooted.

You need to flash the system and boot images from Invisiblek's stock ROM dump. You'll then be unrooted and will be able to accept the update.

Factory reset no longer required if your bootloader is already unlocked? Does TWRP read encypted storage now? Or is that still a problem?

@bmg1001 , good looks, here are more free XDA points to trade in for that pool table, lol.

As far as I know, TWRP still doesn't have decryption fully working just yet, but installing Magisk works fine without any factory resets.

Xposed works fine for me. Make sure you installed the correct Xposed Installer/Manager apk linked in the thread for the Xposed Module. Also, it may take a reboot or two for Xposed to fully activate.

Did anyone manage to disable encryption? I tried everything and failed

Maybe I'm not gathering the information correctly, using the Magisk Module itself doesn't work, sideloading the zip file via the adb fastboot TWRP.img doesn't work either, using the actual Xposed APK installer doesn't work either. I rebooted the phone about 4 times before removing it entirely.
Any chance you can walk me through how you got it installed without the TWRP recovery fully installed?

Alright I got it to work
So I didn't use the APK instead I downloaded the zip from the XDA thread that is specifically for Magisk Module and then added via the modules tab on the left side of the Magisk Module APK.
After I restarted I had the newly installed APK to download and install the proper version of Xposed 88.2 sdk25
Another restart and boom I got the active module notification in green.
Thanks man!

How to install TWRP after Magisk?

How to install TWRP after Magisk?
I have a OnePlus 6 running Oxygen OS 9.0 and I managed to install Magisk by obtaining the stock boot image and using the magisk manager app to patch it to include magisk, then I flashed the patched boot.img using fastboot and ADB.
The reason I did it this way is that every time I tried to boot with twrp.img in order to flash twrp.zip, I would run into a screen saying Qualcomm CrashDump Mode and TWRP wouldn't boot.
Now I want to install TWRP and I was wondering if there is any way of doing it by using Magisk, so I wouldn't have to boot twrp.img.
Any help would be greatly appreciated.

Same problem here. Already tried to boot every version of TWRP without success.

If you have magisk manager with working root.... Then YES you can.... Just download Official TWRP app from GPlay... Open it give root permissions and follow the onscreen instructions.... Thats it...and yes use the zip not the img file

But there's no button to flash, I open the app, select flash recovery, select device, but theres no button to flash it.
See screenshot

do you have fastboot and adb installed on your computer? I assume so as you have oem unlocked to flash magisk, correct?
Copy the TWRP file that ends with .img to your desktop
if so, open a command prompt (windows key +R and type cmd press enter)
type "cd desktop" without quotes and press enter
type fastboot boot "twrp.img" (whatever the file name actually is)
Congrats, you are now in TWRP. But wait, there's more! if you reboot to system or other wise leave TWRP at this point you will revert back to stock. to flash recovery onto your device permanently, install the TWRP.ZIP (The ZIP is IMPORTANT) as it changes the boot on the OP6 to have the TWRP image (oh, by the way, there is no recovery partition on OP6 like previous devices [Thanks A/B partition!])
Now you can reboot to your hearts content. remember if you update OOS, you will lose the custom recovery, so flash the TWRP.zip after every update!

Yes I have fastboot and ADB on my computer (Linux btw), and as I mentioned it the first post, I already tried that, except that instead of booting into TWRP after "fastboot boot twrp.img" I got to a screen saying Qualcomm CrashDump mode (see attached image (the image might not be exactly the same as mine, I found that on the internet because I don't have my computer to reproduce it now)).

super odd. maybe your boot image is corrupt? still doesn't explain why fastboot boot isn't working though... Try bluSpark's TWRP image. it's a solid build and I am not having issues with it.
https://forum.xda-developers.com/oneplus-6/development/kernel-t3800965/page17
or you can also try swapping to the other partition by typing 'fastboot --set-active=_a' (or fastboot --set-active=_b) and booting to that recovery.
if that doesn't work for ya, try and restore stock via fastboot is my only suggestion:

I wonder if this problem has been solved? After having Root without TWRP since last year, I decided to flash TWRP now because I miss having a Nandroid backup. But just like op, right after I type in "fastboot boot TWRP.img", I end up with that Qualcomm crash dump error, resulting in a fastboot boot loop every time I restart the phone. My only recourse is to use the MSM flash tool that reflashes everything and returns the phone into factory stock. In the process wiping out all my data. I don't think there's anything corrupted
EDIT: the problem wasn't the procedure; it was the damned bootable TWRP .img files. I downloaded different TWRP.img versions, and they all failed to flash into temporary TWRP, except for this one that I found here: https://drive.google.com/open?id=1CJoBQ5ZuAExv27XLWwLMFYfHoLEu5YFJ You can use this bootable .img to flash any TWRP version compatible with your device

Hello I'm having magisk root access and official TWRP app but can't use it for NAndroid backup, how can I use the app for backup and fishing custom ROM?

Failed root, stuck on unlocked bootloader warning message.

Hi everyone,
I have tried to get root priviledges following a guide from Droidwin.com to flash Magisk throught TWRP. At the very last step, after flashing Magisk 19.3 throught TWRP when I tried to reboot my phone, it gets stuck on the "unlocked bootloader warning message", which is supposed to disappear after a few seconds and move on to the boot animation.
It seems like I can go to the stock recovery, which shows fastboot and wipe actions. At this point, I can acces the fastboot screen, but the device is not listed using the ADB command "adb devices", nothing is find.
I'm wondering, what can I try to restore the phone ? I thank you in advance for any suggestions.
Here are some additionnal informations:
---Device---
Oneplus nord running OxygenOS 10.5.5, european version.
---What I've done to get in this situation---
Unlock bootloader using ADB
Launch an TWRP image file using ADB
"Try" to root using Magisk 19.3 zip throught TWRP
Power off from recovery (using TWRP touch interface), but the guide tells to click reboot at this step ...
Get stuck on the warning message, not having any boot animation.

Try to boot in Fastboot.
Turn the Nord Off and start it with plus minus and Power.
Boot TWRP with "Fastboot boot "TWRP File name.img" and flash magisk 20.4

Thank you @denndenn.
I'm able to launch TWRP using the ADB command "fastboot boot [twrpfile].img". But when TWRP starts, it asks me for my decryption password, I type it, brief lines of code says "unable to read system/apex" before showing the home page of TWRP. Someone knows what this means, and if that can be the cause ?
I've then tried to reflash Magisk 19.3, which lead to the same result. I couldn't figure out how load Magisk 20.4 to my internal storage in order to flash it trought recovery ... Do you know how to flash a file which is not on my phone ?

Plug your phone to your PC while in TWRP, then you can use adb to push files to your phone, for example with adb push magisk.zip /sdcard. Then, flash Magisk in TWRP.

How about flashing stock boot to see if your OPN boots to system again and then simply load Magisk zip to your internal storage and then flash via TWRP?

Thank you a lot for your suggestions !
Here is the solution in my case :
Because fastboot was working, I was able to flash stock oxygen rom, and get every working, but it needs to erase all your data.
You can find a guide on the XDA topic "[ROM][STOCK][FASTBOOT][OPN] Stock Fastboot ROMs for OnePlus Nord". The rom list have the lastest roms version (09/2020), and the process is super automated.
Have a good week-end XDA !

Blackview BV9900 Update and rooting?

Hi there,
I´ve got an Update for my BV9900.
My Problem is, I can use this BV9900_EEA_S900AA_V1.0_20200522V12_20200523-0035 Version
only for non rooted StockRom.
If I root my phone first, the Update will reboot TWRP Recovery and not his Flashmode.
If I Start the Update on an unrooted System it works.
But then I have the Problem, that I cannot root it anymore with my boot.img and twrp.img.
Can someone help me?
Kind Regards,
Chris

Please install the magisk manager app on your phone and check what if the ramdisk is "no" or "yes"

Ramdisk is Set "no"

The problem is that your phone doesn't support 'ramdisk'. So to root, you now have to patch recovery.img
This will also disable DM verity
Hope i have understood your question properly. Very sorry if i have misunderstood it.

I tried it with my patched File before but get a bootloop.
I'll try it a seconds time with patching from my rooted System

Once you solve the bootloop, before patching the img try the command
adb disable-verity
It might be DM verity that is stopping your phone to boot

I´ve got a TWRP Recovery image that I flashed.
Should I patch these or the recovery from stock Image?
The Stock that I have is the actual running version not the version that I want to update (come from OTA)?

Sorry I didn't see your earlier message. Did you flash the patched TWRP recovery or patched stock recovery?

patched stock from older rom. the newer rom is only on ota.
I´ve no files from this
EDIT:
The ways I tried it:
1. Stock system with installed magisk/TWRP - root works but many functions are buggy
so I tried to flash the new version by OTA. Download fine, but reboot to recovery (not flashing update)
2. Installed OTA (new version) on clean stock first rom.
Update flashing works fine but cannot install root (TWRP/Magisk from patched old recovery version)
Should I try to patch the older twrp(working on stock)?
Or should I disable the option in magisk "perserve force encryption"?
Or can I find any patchable file on running system?
Many questions :-(

When you flashed TWRP did you flash it to both partitions?
fastboot flash recovery_a twrp.img
fastboot flash recovery_b recovery.img

Do you have twrp? If yes flash the magisk zip. By installing twrp, you are removing the root access gains by patching the stock recovery.

LZMA (Elementalx), TWRP, Magisk -> change LOS 18.1 recovery to TWRP in order to get root access,

So, backround is, I want to use AFWall+, which requires root, which I would like to use Magisk for.
In order to get Magisk I need TWRP, I learned so far.
I run LOS 18.1 and I used the lineage recovery/fastboot to flash it (according to the offical LOS-guide).
Changing the recovery is not the easiest thing for me.
Found this thread: https://forum.xda-developers.com/t/from-lineage-recovery-to-twrp-recovery.4253669/
but this seems to be very Samsung specific using Odin (I use a Pixel 4)
I also tried this guide: https://www.droidwin.com/boot-into-recovery-from-fastboot-mode/
but this just "deleted" my OS.
This is why I will be asking a few questions prior starting a new attempt, so please bear with my incompetence
At TWRP I read, I have to install a LZMA ramdisk kernel in order to get TWRP (https://twrp.me/google/googlepixel4.html).
I would go for elementalx, assuming it does support lzma.
From here things are getting tricky for me.
TWRPs guide tells me to get the kernel first, at Elementalx I get the instructions to use TWRP to install
It does say however its not neccessary to install TWRP permanently, but I would like to, because no matter what I want to do with my phone it requires TWRP. So I would like to change the recovery permanently.
The easiest way to do all of this seems to be this guide: https://elementalx.org/how-to-install/
But that will not change my recovery permanently...
What I would do (using a videoguide, because you know, I'm a noobish newbie):
1. Download TWRP img + zip, Magisk zip, Elementalx zip to my fastboot folder
2. Copy the Zips of TWRP, Magisk and Elementalx to my device
3. On my PC -> in the fastboot folder I run cmd as administrator
4. boot into bootloader
5. using cmd -> fastboot boot twrp.img
6. using TWRP -> flash the custom kernel
7. using TWRP -> flash TWRP
8. check if TWRP was proper installed: in TWRP -> boot -> recovery
hopefully the recovery was replaced
9. using TWRP - > flash Magisk
10. reboot
Would anyone please tell me if this will work?
Is there anything I need to do to avoid horrible things to happen?
This is not a request to blame something that could happen on someone afterwards. I just want to minimize the risk...

You can just flash the kernel from fastboot no twrp needed. Just fastboot flash boot boot.img.
You can have magisk patch a boot image then flash it from fastboot as mentioned above.
Usually its just recommended to fastboot boot twrp.img instead of flashing it to the actual device incase you want to revert back and install an OTA.
You can also just download the magisk apk from the device to patch the boot image, flash kernel from fastboot, then reboot with root and have magisk finish doing what it needs to do.

Thank you.
TWRP got stuck booting: I see the logo, "teamwin" and the version used 3.5.2_10-0
Everything was up to date, I'll try it again with an older version of TWRP.

Well, I dont know how to boot into LOS. It just froze on the mentioned screen.
Has anyone a idea what to do?

Ok, I tried it my way - it wont work (of course). Maybe TWRP is still not supported for Android 11.
Now I'll try it your way (thx again).
In order to flash the kernel, I'll have to unzip the elementalx file, I assume. And boot the avaible image, which is called "dtbo.img".
I'll give this a go...

fastboot flash boot boot.img did not work. I renamed the file to boot.img (did not mention this before).
Tried it twice, but nothing worked afterwards, not even recovery and I was not able to turn the device off.
Had to flash LOS again.
I also tried flashing the kernel using sideload while flashing the rom again.
Sideload did work, BUT the wifi was not working at all.
I dont want to bother you, but might there be another way?

That is all. Keep in mind things like wifi might not work if you forget to flash the kernel modules! - Just be sure it is always a 2 step process.

This is what I am experiencing when using sideload. It does install the kernel, but wifi wont work. I guess I do need a working (permanently or temporarly) recovery.

Wifi is usually a kernel module that gets loaded through an init script on boot. It's possible to build the wifi module built-in to the kernel, which makes it so it doesn't have to load separately through an init script.
So if youre not using the stock kernel you'd have to ask whoever makes the kernel you are using.

So, backround is, I want to use AFWall+, which requires root, which I would like to use Magisk for.
In order to get Magisk I need TWRP, I learned so far.
I run LOS 18.1 and I used the lineage recovery/fastboot to flash it (according to the offical LOS-guide).
Changing the recovery is not the easiest thing for me.

Magisk should not be that complicated. All the hard work has been done and can be found in Magisk documentation. There are install instructions for just about any type device and if there is LOS for your device I'm sure it is covered. The latest Magisk is not TWRP flashable the same way as it used to be and newer devices often don't have ramdisk in boot image and root is achieved thru recovery instead. You referenced several threads and guides but no indication of Magisk instructions. Read the Magisk installation instructions for your device type, they're not just suggestions, they work.
